JSN-SR04 pinout
| Name | Description |
|---|---|
| 5V | Positive supply pin of the sensor |
| Trig | Input pin of sensor. This pin has to be kept high for 10us to initialize measurement by sending ultrasonic waves. |
| Echo | Output pin sensor. This pin goes high for a period that will be equal to the time taken for the ultrasonic wave to return to the sensor. |
| GND | This pin is connected to the Ground of the system. |
